Answer:

Step-by-step explanation:

d) (-2 +4i) -( 3 + 9i) = -2 + 4i - 3 - 9i

                             = -2 - 3 + 4i - 9i

                             = -5 - 5i

e)3i(6 - 5i) =  3i *6 - 5i * 3i

                = 18i - 15*i²                    {i² = -1}

                = 18i -15*(-1)

                = 18i + 15

                 = 15 + 18i

f) (-3 + 7i)(1 - 2i) = (-3)*1 - 2i * (-3) + 7i *1  - 2i* 7i

                         = -3 + 6i + 7i - 14i²

                        = -3 + 6i + 7i - 14*(-1)

                        = -3 + 6i+ 7i + 14

                        = 11 + 13i

Answer:

Given : JKLM is a rectangle.

Prove: JL ≅ MK

Since, by the definition of rectangle all angles of rectangles are right angle.

Thus, In rectangle JKLM,

∠ JML and  ∠KLM are right angles.

⇒ ∠ JML ≅ ∠KLM

Since, JM ≅ KL   (Opposite sides of rectangles are congruent)

ML ≅ ML  ( Reflexive )

Thus, By SAS congruence postulate,

Δ JML ≅ Δ KLM

⇒ JL ≅ MK  ( because corresponding parts of congruent triangles are congruent)

Hence proved.

Drake wants to save $750 so that he can take a class on computer analysis for cars. The class is being held on various dates ove
Vadim26 [7]

Answer:

Step-by-step explanation:

Given that Drake wants to save $750 so that he can take a class on computer analysis for cars.

He wants to save 125 per week for 6 weeks.

.Unfortunately, Drake had to take out a little money from his savings in the 3rd week. After 4 weeks, Drake has $470.

If he wants to have 750 after 6 weeks, he has to save \frac{750-470}{2} =140 $  per week

Or alternately he can save same 125 dollars so that he would have 750 $ in

3 weeks.

A: Stay with saving the original amount each week but take the class a week later than originally planned.Option B: Increase the amount of money he saves each week by $15 from his original plan.

Both are right.

c. Both options A and B will allow him to meet his goal.
